Swaziland has the highest prevalence of human immunodeficiency virus (HIV) in the world. Attrition (loss to follow-up and mortality) in people living with HIV/AIDS (PLWHA) already on treatment is a major challenge, undermining achievements of the antiretroviral treatment (ART) programme in Swaziland. The contributing factors to attrition in the Swazi context are unclear. This study aims to (1) estimate attrition from the ART programme 12 months after ART initiation in Swaziland, and (2) determine the predictors of attrition in PLWHA treated with ART in Swaziland. A retrospective cohort study using national baseline data was conducted. A competing-risk Cox proportional hazard regression was used to determine the predictors of attrition. We estimated 10·3% (95% confidence interval 10·1-10·6) attrition in 16 423 participants that initiated ART in 2012. Attrition was significantly associated with sex, age, district, treatment supporter at initiation, co-infection of HIV and TB, functional status, WHO clinical stage, and ownership of facility. Our study can form a base of policies, plans, and service delivery strategies for preventing and controlling attrition in Swaziland.
斯威士兰是世界上人类免疫缺陷病毒(HIV)感染率最高的国家。对已经接受治疗的艾滋病毒/艾滋病患者(PLWHA)而言,人员流失(失访和死亡)是一项重大挑战,有损于斯威士兰抗逆转录病毒治疗(ART)项目所取得的成果。在斯威士兰,导致人员流失的因素尚不清楚。本研究旨在:(1)估计斯威士兰开始接受抗逆转录病毒治疗12个月后ART项目的人员流失情况,以及(2)确定斯威士兰接受抗逆转录病毒治疗的艾滋病毒/艾滋病患者中人员流失的预测因素。利用国家基线数据开展了一项回顾性队列研究。采用竞争风险Cox比例风险回归分析来确定人员流失的预测因素。我们估计,2012年开始接受抗逆转录病毒治疗的16423名参与者中,人员流失率为10.3%(95%置信区间10.1-10.6)。人员流失与性别、年龄、地区、开始治疗时的治疗支持者、艾滋病毒和结核病合并感染、功能状态、世界卫生组织临床分期以及医疗机构所有权显著相关。我们的研究可为斯威士兰预防和控制人员流失的政策、计划及服务提供策略奠定基础。
